The Causes of Heatwaves
As temperatures are expected to reach as high as 40C, experts are concerned about the likelihood of large wildfires racing over the countryside.
Such a fire would devastate the wildlife, according to one expert, who also predicted that Britain would experience conditions comparable to those that are now prevalent in southern Europe.
The Met Office said that there was an extreme risk of wildfires in several areas of England on Monday, with a general notice for Tuesday.
According to Kathryn Brown, the exceptional category hasn't even been used when she previously looked at the Wildfire Index, the Wildlife Trust's director for climate action.
People are hearing reports of terrible flames spreading across southern Europe, and these are the kinds of conditions to which the citizens will be more vulnerable.
The people need to be much more aware of the wildfire risk, and the public needs to be much more informed as well.
Thousands of acres of land have been destroyed by fires in France, Spain, Portugal, and Greece, and residents and tourists have been evacuated as a result.
The National Trust has issued a warning against lighting campfires or grills in wide-open spaces and discarding trash like glass bottles.
